Integrated transceive MMICs for automotive applications were realized in coplanar waveguide technology, using a 0.15 mu m PM-HEMT process. Based on an analytical nonlinear HEMT model, harmonic balance simulations of the entire chip, comprising up to 7 devices, showed good agreement with the measured power performance of the transmit and the receive paths. For the resistive mixer, a DSB noise temperature of only 297 K was measured.
